Yes it does. One angle is Russia on turn 1 builds a sub that can attack Sz14 or Sz15 the following round. It forces Germany to either sit back in Sz14 and build a destroyer to protect against attack from Sz 16. As Germany I would still go ahead and attack Egy. Russia should really be building boots on the ground. 5 Inf+Art+Tank putting the tank in Russia or 3 Inf+3 tanks putting 2 tanks in Russia or the two most common builds for Russia on R1. Putting the tanks in Russia means they can hit PLUS the newly built units in Caucus.
